# Flowg8 · Verify domain TXT

Resolve the challenge and reserve the verified domain for the organization.

409 DOMAIN_NOT_VERIFIED means the expected TXT is not visible yet. 409 DOMAIN_IN_USE means another organization already owns the verified domain. Retrying after DNS propagation needs a new Idempotency-Key.

## POST /v1/organization/domains/{domainId}/verify

Authentication: FLOWG8_ACCESS_TOKEN from Flowg8 sign-in
Required tenant header: X-Organization-Id.
Required user permissions: Administrator role required. The API checks current membership, roles, key scopes and resource permissions on every request. Documentation visibility grants no access.

## Request example (replace example IDs)
